Question

ajutor..va rog mult sa ma ajutati cu ex c si d, multumesc anticipat

Answer 1

x = (33-3)/9 + 2,04 - 0,04 = 30/9 - 2 = 30/9 - 18/9 = 12/9 = 4/3

y = 18/5 * [6/9 + (16-1)/90] = 18/5 * (2/3 + 1/6) = 18/5 * (4/6+1/6) = 18/5 * 5/6 = 3

(x+y)/2 = (4/3 + 3)/2 = (4/3 + 9/3) = (13/3)/2 = 13/6

√xy = √(4/3*3) = √4 = 2
